	<title>CSS Masking: Dynamic change of clipPathUnits on clipPath</title>

	<desc class="assert">The clipPathUnits attribute on the clipPath
	element gets changed dynamically from objectBoundingBox to userSpaceOnUse.
	This reduces the clipping area from a size much bigger than the document to
	the size of the green rectangle. A green square should be visible.</desc>
</g>
<clipPath id="clip1" clipPathUnits="objectBoundingBox">
	<rect width="200" height="200"/>
</clipPath>

<rect width="400" height="400" fill="red" clip-path="url(#clip1)"/>
<rect width="200" height="200" fill="green"/>

<script>
var clip = document.getElementById("clip1");
var enumeration = clip.clipPathUnits;
enumeration.baseVal = 1; // Switch to userSpaceOnUse!
</script>
